HELP ME PLeaseee!!!!

Answer 1

Answer:

x= 8.5, 2x=17, (9x+5)=81.5

Step-by-step explanation:

since the sum of the interior angles of a triangle is 180 degrees, you must add all of the angles and set them equal 180:

$2x + 2(9x+5) = 180$

next distribute the 2 to 9x + 5.

$2x + 18x + 10 = 180$

next combine like terms (2x and 18x) and subtract 10 from 180.

$20x = 170$

finally, divide 170 by twenty.

$\frac{20x = 170}{20}\\,x=8.5$

the final answer is x=8.5

once x is determined, you can solve 2x and 9x+5.

$2(8.5)=17\\\\9(8.5) +5 =81.5$
